Preowned, used vintage set.  This is not a complete set, I am missing the manual that lists all the parts, I'm not sure what is missing, but there are extra pieces from additional sets here too.  A few of the soldier figures are damage.  New rubber bands are needed for the towers and weapons, but they appear to be in good condition.  The box is included, but it is flimsy and the bottom half is pretty worn.

See the pictures for what is included.
